Hex Key (Imperial) Bondhus 1/4 in, length 133 mm, ball end

Bondhus 1/4 in imperial hex key, 133 mm long with a ball end designed for angled engagement with hex fasteners. Constructed from solid steel to provide reliable torque transfer for tightening and loosening inch-sized hex bolts and screws. The longer shank improves reach into confined or recessed areas while the ball end enables access at an angle when straight entry is not possible.

Advantages

This 1/4 in Bondhus hex key offers a balance of length and control: the 133 mm shaft increases reach without compromising hand leverage. The ball end allows up to approximately 25–30 degrees of off-axis engagement for faster insertion and removal in restricted spaces. Solid steel construction ensures durability and consistent torque delivery, and the precision-formed hex profile reduces rounding of fastener corners.

Suitable for

• Assembly and disassembly of machinery and equipment with inch hex fasteners
• Maintenance tasks in tight or recessed spaces
• Automotive, industrial and workshop applications requiring angled access
• Furniture assembly and field service work using imperial hex screws

Key specifications

• Drive size: 1/4 inch (imperial)
• Overall length: 133 mm
• End style: ball end for angled engagement
• Material: solid steel construction for torque transfer
• Intended use: hand tool for hexagon fasteners (inch-sized)

How to use

Insert the hex key into the matching 1/4 in hex socket of the bolt or screw. For straight access, seat the hex key fully to ensure full contact between the key and the fastener. When direct entry is obstructed, use the ball end at a slight angle to engage the fastener; apply steady torque while maintaining alignment to avoid cam-out or rounding. Withdraw the tool and inspect the fastener periodically during repeated use to confirm secure engagement.

Usage recommendations

Choose the 1/4 in Bondhus hex key when you need additional reach or angled access to inch hex fasteners. Use the ball end for initial engagement or removal in restricted locations, and switch to the straight portion of the key for maximum torque when space allows. Keep the key clean and free of burrs to maintain proper fit and minimize fastener wear.
